Abstract
Breakthrough pain (BP) is defined as transitory pain that occurs on a background of relatively well controlled baseline pain. This pain character can join pain of tumour disease origin but not only that one.
Question to specify the character of pain should be common in daily contact with a patient. To resolve this problem it seems necessary to provide pa- tients wit rescue mediation with rapid 30 minute onset.
The article comes with analgetics review according to WHO classification and suitable for BP and available in the Czech Republic. From the point of fast onset view we are looking for new approaches and application routes practical also for outpatient departments.
Intranasal fentanyl offers such option. When pharmacotherapy is not effective any more, mainly in oncology new invasive methods are being explo- red.
